Allen confirmed Realm/global/environment are 1:1:1. 119893 3 ian 2015-04-24 19:37:11 +0000 So I read through that thread, and I don't really understand why this affects HTML. Shouldn't the ES spec take care of maintaining its invariants? HTML shouldn't need to know anything about realms and certainly shouldn't need to know anything about global environment records, surely. 119921 4 annevk 2015-04-27 06:28:26 +0000 Ideally? Yes! See also bug 25981... 120101 5 ian 2015-05-05 21:31:40 +0000 Bug 25981 is mostly about plugging into the defined external-facing hooks in the ES6 spec. I don't see how this is an external-facing hook. Global environment records and Realms seem to be internal details of the ES language. 120112 6 ian 2015-05-05 22:02:38 +0000 Also, would I create a new Realm when I create the new Window anyway? Normally when I create a Window I do so by invoking ECMAScript's Initialization(), which calls InitializeHostDefinedRealm(realm) with a new realm that was created for me, and I never even see the environment records. But I can't do that here because calling Initialization() manipulates the execution context stack. 120113 7 ian 2015-05-05 22:33:00 +0000 I meant "Also, how would I...". 120114 8 ian 2015-05-05 22:49:14 +0000 Actually no, when I create a Window object I don't call Initialization(). That's for creating the event loop. I'm not sure what I do when creating a Window. I'm not sure how I create a Window. InitializeHostDefinedRealm() isn't called by any other algorithm in the JS spec. 120117 9 ian 2015-05-05 23:23:23 +0000 Ok see bug 25981. I guess I do call Iniitialization even for document.open()? 124433 10 d 2015-12-15 15:35:54 +0000 https://github.com/whatwg/html/commit/cf0355d7e0e229b98f7fbd51b8c7608010c787f5
